Using lower order elements or thickening the mesh it is not an option. I &#8220;only&#8221; have to reduce the RAM requirements of the analysis in 2.6Gb aprox (from 33.5Gb to 31.9) so out-of-core solving is possible (not even thinking about in-core solving).<\/p>\n<p>Its remarkable that I dont have RAM related errors while running structural analysis with the same exact model. Thats why I think there might be an option to reduce analysis RAM requirements for the modal-spectral analysis I am trying to execute. ChatGPT has given me the following solutions:<br \/>&#8211; Reduce the number of iterations<br \/>&#8211; Use a more efficient solver method<br \/>&#8211; Use lower precision settings<br \/>&#8211; Explore the memory optimization settings<br \/>&#8211; Reduce the amount data written to output files<br \/>&#8211; Use solver-specific options to control memory usage<br \/>&#8211; Run the simulation in batch mode without the graphical interface.<\/p>\n<p>Sincerely, I dont know how to implement any of these option, as I am a relatively new user of Ansys and I am experimenting my first RAM issues. In fact, I dont even know if any of these solutions will be helpful for my problem. I would realy appreciate some advice from more experienced users.
